JOHN HOWARD KRESS, OF LOUISVILLE, KENTUCKY.

CUTTER.

Application filed September 26, 1919.

T 0 all whom it may concern:

Be it known that 1, JOHN H. Knnss, a citizen of the United States,residing at Louisville, in the county of Jefferson and State ofKentucky, have invented new and useful improvements in Cutters, of whichthe following is a specification.

This invention relates to cutting or shearing devices and moreparticularly to a cutter for shearing rivets and bolts and has for aprimary object the provision of a cutter in which the knives are soarranged that a clean flat out will be accomplished.

In the majority of bolt and rivet cutters, the former are not out iiushwith the surface of the nut, a V-shaped portion usually projecting andwhich must be filed down to provide a neat finish. This is especiallydesirable in carriage, automobile work and other light industries.

It is the purpose of the present invention to provide a cutter forshearing bolts, which will cut the bolt flush and flat with the outersurface of the nut, rendering it unnecessary to finish the same with afile. It is also the purpose of the invention to provide a device forshearing rivets in which the rivet will be cut flat and smooth and asuflicient portion of the rivet (about inch) left projecting beyond theobject to be riveted, so that a proper riveting may be affected and thebest results accomplished, the device being so constructed and arrangedas to leave this amount of rivet for this purpose. It furtherfacilitates the operation of riveting by providing a smooth fiat out.

For the accomplishment of the above and other objects, the inventionresides in a number of knives and cutting edges and their relativearrangement with relation to the pivot which connects the jaws carryingthe knives.

Other objects and advantages of the invention will appear as thefollowing description is read in connection with the accompanyingdrawings.

In the drawings:

Figure 1 is a plan view of a tool embodying the present invention.

Fig. 2 is a detail plan view of the connecting bar carried by one of thejaws.

Figs. 3 and 1 are similar views of the jaw portions of the pivotedmembers.

Referring to the drawings in detail, wherein like characters ofreference denote corresponding parts, the invention includesSpecification of Letters Patent.

Serial No. 326,424.

a pair of handle members, which are indicated at 1 and 2.

The handle member 1 is provided at one end with a knife or cutting jawS, which cooperates with a jaw 4;, carried by the handle member 2. Thesejaws are pivotally secured together, as indicated at 5, the pivotpassing through the jaws and through a plate or bar 6, the opposite endsof which are connected to the jaw 3 of the handle 1, the jaw 4 operatingbetween this plate and the jaw 3. The jaws 3 and 4 provide a boltcuttingtool, having their opposed edges beveled and sharpened to providecutting edges 9. These cutting edges operate on the same plane and areof the same relative curvature, so that they may be forced together toprovide a straight flat out, and owing to their position, may cut closeto the outer face of the nut. To provide for the proper relativeposition of the cutting edges 9, the jaw 3 is secured upon the face ofthe handle member 1, one of the bolts 7 passes through an opening 7 ofthe jaw and through a similar opening in the handle member 1. To preventpivotal movement of the jaw 3, there is provided a pin 7", which passesthrough the jaw 3, the handle member 1 and the connecting bar 6.

Also carried by the jaw 4, is a knife 8, the latter being positionedupon the undersurface of the jaw between the latter and the handlemember 1, and for the purpose of acc'ommodating the knife 8, the handlememher 1 is recessed, as indicated at 10, the said knife 8 operatingacross the bottom of this recess. The handle member 1 is provided withan opening 11, which communicates with the recess 10 and the walls ofthis opening provide a cutting edge for cooperation with the knife 8, toform a rivet cutting tool, the thickness of the handle member 1 at thispoint serving as a gage to regulate the length of the rivet leftprojecting after the cut for the purpose of leaving sufficient materialto accomplish a proper riveting 7 operation.

It will be seen from the foregoing description and the accompanyingdrawings, that the invention provides a double tool, One of which willeffectually cut a bolt clean and flush with the outer surface of thenut, and the other cutting a rivet, leaving a portion of the sameprojecting beyond the object to be riveted. The invention is further soconstructed that it cannot cut over-sized bolts claimed is:

or rivets, so that it cannot be subjected to undue strain or abuse.

As the knife 9 of the jaw 3 is removable and may be renewed orsharpened, when necessary, it is also desirable to provide for therenewal of knives or cutting edges 9 and 8. For this purpose the jaw 4is separate from the handle 2, the adjacent ends of the said jaw andhandle overlapping and being secured by bolts or screws 12.

The invention is susceptible of various changes in its form, proportionsand minor details of construction and the right is herein reserved tomake such changes as properly fall within the scope of the appendedclaim.

Having described the invention, what is A cutter comprising a pair ofmembers pivoted together, handles extending therefrom, one of saidmembers being provided with a relatively wide head having an opening andalso having an arcuate shaped inwardly curved jaw extending therefrom, aconcaved cutting edgefor said jaw, a relatively narrow jaw extendingfrom the other member, oppositely disposed convexed cutting edgesprovided upon the narrow jaw, one of said convexed edges cooperatingwith the cutting edge of the wide jaw and the other cutting edgecooperating with the walls of the opening formed in the last mentionedjaw.

In testimon whereof I affix my signature.
